PNEUMATIC CASH CARRlER APPARATUS.

SPECIFICATION forming part of Letters Patent No. 378.533, dated February28, 188

Application filed April 13, 1887. Serial No. 234,669. (No model.)

To ctZZ whom it may concern:

Be it known that I, WILLIAM A. Wnnnnn, of Medford, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Pneumatic Gash-Carrier Apparatus, of which thefollow- .ing is a full, clear, and exact description.

This invention relates to improvements in pneumatic cash-carrierapparatus, and has for its object the indicating or signaling to theperson who has transmitted the carrier or other article through the tubewhen such carrier or other article arrives at or near the delivery endof the tube or at some desired point or place in the tube, or has beendischarged at the delivery end of the tube; and the invention consists,in combination with a pneumatic tube for the transmission of a carrieror other article therethrough, of an independent and supplementary tubeor passage having communication with an indicator or signaling orsounding device at or near the transmitting end of the pneumatic tubeand with a bellows or collapsible and expansible chamber, which isarranged to be operated by means of an arm or lever extending into thepneumatic tube in position for the carrier, &c. as it is transmittedthrough the pneumatic tube, to strike and abut against such arm or leverand cause said bellows or collapsible and expanding chamber to close oropen, and thus cause air to pass through the independent andsupplementary tube or passage and operate the indicator or signaling orsounding device, and thus notify or indicate to the person whotransmitted the carrier, 850., that it had been delivered from thepneumatic tube or had passed a desired point or place along the tube,all substantially as hereinafter fully described, reference being had tothe accompanying sheet of drawings, in which-= Figure 1 represents inside view a pneumatic tube for the transmission of cash-carriers orother articles therethrough from one station to another,having attachedthereto the present invention. Fig. 2 is a detail vertical section ofthe bellows or collapsible and expansible chamber, showing its means ofcommunication with the independent tube or passage and its connectionwith the pneumatic tube for operation by the carrier or other articleasit is transmitted through the tube; Fig. 3, a detail vertical sectionshowing the bellows or collapsi ble and expansible chamber as operatedby the carrier in the pneumatic tube. Fig. 4 is a partial side view andpartial section of the signaling or indicating apparatus. Fig. 5 is adetail vertical section similar to Fig. 2, to be hereinafter referredto. Fig. 6 is a detail vertical cross-section of the signaling orindicating device at right angles to that of Fig. 4. Fig. 7 is avertical sectional View of one end of the pneumatic tube and itsstandard on line 7 7, Fig. 1.

In the drawings, A represents a pneumatic tube for the transmission of acash-carrier or other article, 800., therethrough, the tube at each endbeing attached to a separate standard, B, which is secured to anysuitable table or desk, as at a, and has a chamber, 0, with which saidtube communicates, which in turn communicates with any suitableoperatingbellows or other air-motor.

D is a valve, hinged at b to the standard and adapted to close and openthe opening E to the standard -head F, through which opening E thecarrier or other article to be transmitted is inserted for suchtransmission and delivered after having passed through the tube, allsubstantially as is usual and well known in pneumatic cash-carrierapparatus, and needing no more particular description herein.

G is a tube which extends from one end, H, of the pneumatic tube alongwith it and toward the other end, K. At the end H this tube G isconnected to a small bellows or collapsible and expansible chamber, L,which is attached to and supported by the pneumatic tube A, the tube Ghaving communication therewith, as shown inFigs. 2 and 5. The bellows Lis secured byscrcws d to an arm, M, of a strap, f, which strap encirclesthe tube, and is held securely thereon by a screw-nut, g, passingthrough the two ends of the strap by which the bellows L is secured tothe pneit matic tube. Attached and pivoted at hwithin a longitudinalslot, m, of the pneumatic tube, below the bellows L, is an arm or lever,N, in two parts or arms, a r, hinged together, one part, 1', extendingtoward and under the bellows L, and the other part, n,throngh the slotin into the pneumatic tube, and when the bellows L is open and the partsin their normal position such arm projects into the pneumatic tube, asshown more particularly in Fig. 2. The hinge -joint of the two arms a ris such that when in the position shown in Fig. 2 the two square ends 8s of each arm will abut against each other for the proper operation ofthe lever, and yet allow the arm n to swing upward on its pivot,independent of the arm 1', into the position shown in Fig. 5. The arm 7'is held to the bottom board, P, by the staple t, to keep it in positionready for proper operation on the bellows, as will be described. Theother end, K, of the independent tube G is attached to an arm or block,Q, secured by a bracket, to, to the pneumatic tube A, and communicateswith a chamber or passage, R, in said block, which chamber or passageopens into and communicates with a chamber, T, in a vertical cylinder,U, in which is adapted to move freely up and down a piston or valve, V.This piston has a central vertical arm, o,which extends upward throughan opening, w, in the top, and engages by an eye, 3 with a springwirearm, WV, having a knob or block, Z, on its outer end and pivoted at a toan arm, 12, of the cylinder. Attached to an upright arm, (2, of thecylinder is a bell or gong, f, which is in position for the knob Z ofthe spring-arm WV, as such spring-arm is swung up, to strike against thebell or gong, as shown in dotted lines in Fig. 4, and sound the same, asusual in striking bells or gongs.

The operation of the apparatus is as follows: The carrier or otherarticle to be transmitted through the pneumatic tube is placed in thetube in the head F of the standard B and the valve D closed, and thenthe bellows or other air-motor operated, which forces the carrier alongthrough the pneumatic tube. When the carrier reaches the part of thepneumatic tube where the bellows L is attached, it strikes against thearm n on the lever N, and as it continues its movement it presses sucharm down, swinging it on its pivot h and swinging its arm r up,which inits movements moves up the bottom board, 1 of the bellows L and closesthe same, as shown in Fig. 3. As the bellows L closes, the air from suchis forced along the independent tube to and into the chamber R and thecylinder chamber T at the transmitting end K of the tube, which raisesthe piston V, and through it the springarm W, which strikes the bell fand sounds the same, thus notifying the person who transmitted thecarrier, &c., that the carrier has arrived at the desired point in thepneumatic tube or has been discharged at the delivery end. After thecarrier has passed the arm a the bellows L opens or falls to its normalpo sition, ready for operation when another car rier is transmittedthrough the tube. When the carrier, &-c., is transmitted through thepneumatic tube in the reverse direction,as the carrier reaches the pointwhere the arm n is, it strikes such arm and swings it up on its pivot,in this movement not affecting its arm r, so that the carrier passesfreely by the same, the arm lying in the upper part of the slot 1%,

as shown in Fig. 5. Thus the person operating the apparatus to transmitthe carrier, &c., through the pneumatic tube is notified by the soundingof the bell or gong that the carrier, &c., has been delivered or arrivedat the predetermined point,when he can cease operation of the bellows orother air-motor.

The bellows or collapsible and expansible chamber L can be located atany desired point on the pneumatic tube for operation thereof, at ornear the delivery end or at any distance back therefrom, but should benear enough to the delivery end for the carrier, 850., if the op eratorceases operation of the motor, to be carried along the balance of thepneumatic tube and delivered therefrom by its momentum.

Although the pneumatic tube shown in the drawings is adapted to transmita carrier, 820., therethrough from each end, the signaling or indicatingdevice is only arranged for operation by the transmission of a carrier,8m, one way-that is, from the end K to the end H- and for operation theother way the independent tube and its parts must be duplicated; or, ifonly one independent tube is used, the be1 lows L and the signalingdevice should be duplicated and a suitable valve arrangement combinedtherewith for operation either way-- for instance, as shown anddescribed in a joint application, No. 229,192, filed February 28,

' 1887, of myself and V. S. Pain for Letters Patent of the United Stateson pneumatic cash-carrier apparatus.

Any suitable sounding device can be used, such as a whistle or anythingthat can be operated from the passage of air through the independenttube or passage; or, in lieu of a sounding device, any suitableindicator for sight observation can be used; also, any suitable bellowsor collapsible and expansible chamber can be used, and the lever can bearranged to operate it in any suitable manner, and in lieu of being intwo parts it can be in one; but it should be so adjusted that afteroperation by the carrier, 8m, it will return to its normal position foroperation again, and also will allow the carrier to pass by it whengoing in the reverse direction without affecting the bellows; also, inlieu of being independent of the bellows L, it can be attachedpermanently to the moving board or be an ex tension of the same.

The bellows L and the signaling device can IIO in any suitable positionaway from the tube;

also, in lieu of closing the bellows L for the operation of thesignaling device, it can be arranged to operate in the reversethat is,to open or as an exhaust-bellows; but in such case the other partsconnected therewith should be reversed accordingly.

Having thus described my invention what I claim is- 1. The combination,with a pneumatic tube for the transmission of a carrier, &c.,therethrough, of an independent tube or passage.

having communication with'a suitable indicator or signaling or soundingdevice and with a bellows or collapsible and expansible chamber, saidbellows or collapsible and expansible chamber being suitably connectedto said pneumatic tube for operation by the carrier, 850., as it travelsalong the pneumatic tube.

2. The combination, with a pneumatic tube for the transmission of acarrier, 4320., therethrough, and an independent tube or passage havingcommunication with a suitable indicator or signaling or sounding deviceand with a bellows or collapsible and expansible chamber, of a pivotedlever arranged to act upon said bellows or collapsible and expansiblechamber and extendinginto the pneumatic tube in proper position for thecarrier, 810., as it travels along said-pneumatic tube, to strike orabut against said lever and operate said bellows for the purposespecified.

3. The combination, with a pneumatic tube for the transmission of acarrier, 820., therethrough, and an independent tube or passage havingcommunication with a suitable indicator or signaling or sounding deviceand with a bellows or collapsible and expansible chamber, of a jointedpivoted lever, one of its arms arranged to act upon said bellows orcollapsible and expansible chamber, and its other arm extending into thepneumatic tube in proper position for the carrier, 8m", as it travelsalong said "pneumatic tube, to strike against said lever and operatesaid bellows, for the purpose specified.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
